Cypress Semiconductor Corp. (Nasdaq: CY) today announced that the U.S.
Patent and Trademark Office (PTO) has completed its re-examination of
Cypress's U.S. Patent No. 7,142,477 and confirmed its validity. In
particular, the PTO confirmed without amendment both of the claims being
asserted by Cypress in the International Trade Commission's (ITC) patent
infringement case against GSI Technology Inc., and allowed 64 new claims
added by Cypress during the re-examination.
"The Patent and Trademark Office's re-examination review was
exhaustive," said Dana Nazarian, executive vice president of Cypress's
Memory Products Division. "The '477 patent was re-examined in light of
all of the prior art submitted by GSI in its re-examination request, as
well as prior art used by GSI in its defense of the ITC investigation.
The PTO ruling confirms what we've known all along - that the '477
patent is rock-solid.
"In a November 2011 press release, Lee-Lean Shu, the CEO of GSI, said
'we are confident that completion of the re-examination will result in a
final rejection of these claims,'" Nazarian continued. "The PTO not only
reaffirmed the '477 patent, it allowed 64 new claims. It is now clear
that Mr. Shu's prediction about the '477 patent was wrong."
In June 2011, Cypress filed a complaint with the ITC alleging that GSI's
SigmaQuad-II, SigmaQuad-III and SigmaDDR SRAM families infringe four
Cypress SRAM patents. The case was later expanded to include GSI's
standard synchronous and ZBT SRAMs, as well as a proprietary product
made by GSI for its largest customer. The complaint seeks an exclusion
order from the ITC that would prevent the importation of all infringing
GSI SRAMs. The trial has been completed, and the ITC is expected to rule
on this case in late July.
